Sounds great.

This exhaust sounds amazingly deep for a 4 cyl when paired with a catless DP. It’s great it didn’t drone a whole lot but there is a little when cruising but it didn’t bother me. Was pretty easy to install too.

So Far So Good

Went from a 2.5 straight pipe to this after going big turbo and decat to quiet it down a little, but maintain as little restriction and backpressure as possible. Definitely did the job

I was weary about clamps instead of welds but the muffler is straight off the downpipe, so nothing after that really matters.

Fitment wasn't the easiest, but it came with some much nicer, smaller, stiffer rubber hangers than the stock ones.

As far as MAP goes, shipment was quick as always.

This is the 5th item I've purchased from these guys so far, and they continue to exceed my expectations.
